Server Sending Invalid Match Key Parameters for ViewCategory Event

Hi @rootid,

Thanks for reaching out about Facebook for WooCommerce! I’ll be happy to help.

We’ve recently reached out to Facebook directly to try to get some clarity regarding the “Invalid Match Key” warning. While no specific resolution has been provided, we do now know this from their replies:

• this warning only occurs with server to server events (added in Facebook for WooCommerce v2.0)
• it can be the result of a platform issue – which wouldn’t be fixable from within the plugin
• Facebook will not share more specific event data for privacy reasons
• there aren’t any events in the plugin’s logs with missing user_agents or ip_addresses

Facebook has assured us that they’re looking into providing more information for this error in a future release, such as showing the affected URL and the parameter and what is wrong with it. They did also mention, however, that even with some additional details, it would not likely be able to be resolved by the plugin, as it can be at the platform level.

They weren’t able to pass along an expected date for release, though did mention that they usually see some features/improvements added after the holidays.

It seems that at this moment, we’ll need to wait for this release before looking at the Invalid Match Key parameter further. Please do let us know if you hear something different directly from Facebook!

Is there anything else that I can help with for now?

Thanks,

Jennifer
